The threading on the C-presses are extremely sloppy/loose and the C-press C opening is larger than the opening in the Mercedes tool so both of those by themselves conspire to cause some misalignment.
The bottom plate pointed to in my pic by the Yellow Arrow is an as cast plate and not precision machined.
The comparison is between a $375 Special Too built to do a specific job and a generic multipurpose tool that can be had for around $30
The third choice is the JTC remover and installer at around $120 that needs to be used with a Hydraulic Press. If you have no Hydraulic Press you would need to take it to a shop that has one and pay them to press in your Ball Joints.
One of our members made the Ball Joint Press in the 2nd pic.
